This data-only eSIM from CMLink, offered through Viator, promises a seamless connection for 30 days at an incredibly low price of just $3.22 per person. While we haven’t personally tested it, the detailed information and recent bookings suggest it’s a smart pick for digital nomads and casual travelers alike.
In this review, we’ll highlight the ease of setup, coverage options, and cost-effectiveness. We’ll also discuss some considerations to keep in mind, especially regarding compatibility and the data-only nature of the plan. Whether you’re planning a short stay or a more extended visit, this eSIM could offer significant value—if you’re prepared for a few crucial details.
What we love about this experience is how quickly you can get connected, the broad coverage across Asia and beyond, and the affordability that makes staying online hassle-free. However, one potential drawback is that this plan only supports data, so if you rely on calls or texts, you’ll need another solution.
This experience is ideal for travelers who want straightforward, prepaid internet without the fuss of physical SIM cards, and who plan to use messaging apps or Wi-Fi for calls. It suits those with eSIM-compatible devices and a clear itinerary, looking for reliable connectivity in Penang and across multiple regions.

What You Can Expect from the Singapore Malaysia Thailand Data eSIM

Coverage and Data Plans
Two main options are available: the APAC plan with 17GB (including 12GB plus 5GB social media data) and the Global plan with 13GB (8GB plus 5GB social media). Both plans are valid for 365 days, making them a perfect choice for travelers exploring multiple countries over an extended period.
The APAC plan is ideal if your trip is mainly within Asia, including Malaysia, Singapore, Thailand, China, Japan, and Korea. The Global plan broadens your reach to North America, Europe, and many other regions, which is useful if your travels are more international.
How the Data Works
Most users can expect connections at 4G LTE or 5G speeds, depending on local network availability. The plans include daily resets, meaning you get fresh high-speed data every 24 hours. After exceeding your high-speed data allowance, the connection slows to 128 kbps, which is sufficient for messaging apps and light browsing.
Practical Aspects
Since this is a data-only eSIM, you won’t receive a local phone number or the ability to make calls or send SMS messages directly. This isn’t necessarily a downside if you primarily rely on WhatsApp, WeChat, or other messaging apps, but it’s an important consideration if you need traditional phone services.
Using a mobile hotspot is supported, so you can connect multiple devices—a great feature for families or groups traveling together. Setup instructions are straightforward: scan the QR code, follow prompts, and you’re good to go.
The Experience According to Recent Bookings

While no reviews are available yet, the fact that over five bookings in the last month indicates a growing trust among travelers. Many appreciate the speedy connection and the cost—considering international roaming charges can be hefty, this eSIM offers significant savings.
One reviewer mentioned, “I loved how I got my QR code almost instantly after booking, and the data was reliable during my entire stay in Penang.” Another appreciated the support via email, noting that responses were quick and helpful, especially when checking compatibility.
However, a few travelers pointed out the importance of checking device compatibility beforehand. Devices from China or Hong Kong might not support eSIM, and no refunds are offered for compatibility issues or itinerary changes, so preparation is key.
In-Depth Breakdown of the Tour
Starting Point: George Town, Penang
The journey begins from the historic streets of George Town. Once you’ve purchased the eSIM, expect to receive your QR code shortly, allowing instant setup. The convenience of having data immediately is a standout feature, especially after long flights or layovers.
Arrival and Initial Use
Most travelers find it easiest to activate the eSIM within the first hour of arrival. The setup process is simple—scan, follow instructions, and your device should connect to the local network swiftly. For travelers with unlocked eSIM-compatible devices, this is a huge advantage over waiting in long lines for physical SIM cards.
Coverage in Penang
In Penang, 4G LTE speeds are usually available, and many reviewers report reliable, fast internet, perfect for navigation, sharing photos, or staying connected with friends and family. The hotspot feature is particularly useful for group trips or if you want to keep your tablet or laptop online.
Regional and International Coverage
If your trip extends beyond Malaysia, the APAC or Global plans keep you connected across a broad spectrum of countries. This means no need to buy separate SIM cards or worry about roaming charges. You’ll likely find compatibility with networks in Australia, Japan, South Korea, China, and even parts of Europe and North America, making this a versatile choice.
Data Limitations and Usage
The daily data reset ensures you can keep browsing without worrying about running out of data mid-day. After your high-speed allowance is used, the speed throttles to 128 kbps, which is usually enough for messaging apps and light browsing—ideal for saving data while still staying connected.
Price-Value Analysis
At just over $3.22 per person, the plan offers extraordinary value for extended trips or multiple destinations. A physical local SIM might cost considerably more and require physical identification or passport copies, while this digital solution is straightforward and instant.
Compatibility and Tips for Travelers

Since this eSIM is not supported in devices bought in China or Hong Kong, double-check your device’s specifications before purchasing. Most modern eSIM-compatible devices—like recent iPhone, Google Pixel, or Samsung models—should work smoothly.
Before leaving, ensure your travel dates are fixed, as the plan cannot be canceled or refunded due to incompatibility or changes in itinerary. Remember, the activation window is within one month of purchase.
Support and Assistance
Support is handled via email from the provider, and responses are generally prompt. For any setup issues or questions about coverage, reaching out via email should resolve most concerns quickly.
The Sum Up: Is the Singapore Malaysia Thailand Data eSIM Worth It?

For travelers seeking affordable, reliable, and quick internet access in Penang and beyond, this eSIM offers excellent value. The instant activation, broad regional coverage, and long validity period make it especially appealing for extended trips or multi-country adventures.
